Overview

Common risk factors in the development of esophageal cancer are tobacco smoking, alcohol, gastroesophageal reflux disease, and Barrett's esophagus.

Decreased risk

  • Risk appears to be less in patients using aspirin or related drugs (NSAIDs).
  • The role of helicobacter pylori in progression to esophageal adenocarcinoma is still uncertain, but, on the basis of population data, it may carry a protective effect. It is postulated that helicobacter pylori prevents chronic gastritis, which is a risk factor for reflux, which in turn is a risk factor for esophageal adenocarcinoma.
  • Diets high in cruciferous (cabbage, broccoli, cauliflower) and green and yellow vegetables and fruits are associated with a decreased risk of esophageal cancer.
